Ensemble Music
The majority of the Ophee Collection contains music for solo guitar or, occasionally, for two guitars. There are also many songs with guitar accompaniment, however, and a few items for guitar in various types of ensembles. Note that the following are individual parts for the various instruments in the ensemble:
